Spectra Line, like fishing line?

Did you weigh the bare airframe before you started? I can't see how your mods saved you 13 ounces (based on 2 pound 2 ounce weight that is common). Did you remove some of the wood or something?

I'd have to guess that the gear and wheels were a huge savings, but what else was a big difference?

At 25 ounces, you could drop another ounce or two by going to a light 15, and still have plenty of power.

The glow or electric conversion "kit" sounds cool. You'll have to post some pics when you get that all done too.
